The application procedure of preflush for well cementing
油氣井注水泥前置液使用方法 -
The study results indicated that, arranged in the order of magnitude, the degrees of the effects on the cementing strengths of the two interfaces were the system, emulsion, main emulsifier, fluid loss control agent and white oil respectively ; the cementing strength would be doubled and redoubled after being cleaned by preflush, especially by the system, emulsion and fluid loss control agent ; and, along with the increase in the mix slurry ratio, the initial and final set times of slurry would be obviously lengthened and the compressive strength of bond cement would be remarkably reduced or the slurry wouldn ' t be even set
研究表明：對兩界面膠結強度的影響由大到小依次是體系、乳狀液、主乳化劑、降濾失劑、白油；前置液清洗后，膠結強度成倍提高，尤其對體系、乳狀液和降濾失劑清洗效果最佳；隨混漿比的增大，水泥漿初凝和終凝時間明顯延長，水泥石抗壓強度明顯下降，甚至不凝。 -
Then it gives some suggestion on the determination of operation discharge and preflush rate and some technical problems in operation
通過實際施工資料的統計，對施工排量和前置液量的確定等施工中需要改進的技術問題，提出了建議。
